CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to the Community Plant Variety Rights application number 2015/1574, filed Jul. 8, 2015, which is herein incorporated by reference.

BACKGROUND OF THE INVENTION

Parentage: The Vanda variety ‘SPCDW1510’ is the result of a planned breeding program. The new variety originated as a seedling from the crossing of an unnamed Vanda seed parent (not patented) with an unnamed Vanda pollen parent (not patented). Both parents were developed by, and are owned by, the inventor and were never commercially released. The crossing was made by the inventor in his research greenhouse in Bangphra, Thailand in December of 2005.

The new variety was first selected in November of 2009, in a research greenhouse in Bangphra, Thailand belonging to the inventor. After identifying the new variety as a potentially interesting selection, the inventor continued confidential testing and propagation of ‘SPCDW1510’, assessing stability of the unique characteristics of this variety.

Asexual Reproduction: Asexual reproduction of the new cultivar ‘SPCDW1510’, by way of mericloning, was first initiated in May of 2010 at a commercial laboratory belonging to the inventor in Bangphra, Thailand. Access to all plants was restricted, as plants were kept in a greenhouse not open to the public, and tissue culture plantlets were in a laboratory belonging to the inventor, and not accessible to the public. Through six subsequent generations, the unique features of this cultivar have proven to be stable and true to type.

SUMMARY OF THE INVENTION

The cultivar ‘SPCDW1510’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype. The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘SPCDW1510’. These characteristics in combination distinguish ‘SPCDW1510’ as a new and distinct Vanda cultivar:

-   -   1. Vanda ‘SPCDW1510’ exhibits sepals and petals which are pink         and margined red-purple; and     -   2. Vanda ‘SPCDW1510’ exhibits sepals and petals which are         heavily dotted and blotched red-purple; and     -   3. Vanda ‘SPCDW1510’ exhibits sepals with a prominent red-purple         irregular tessellation pattern; and     -   4. Vanda ‘SPCDW1510’ exhibits a labellum with purple lateral         lobes which are striped red-purple, and a dark red-purple         central lobe.

BRIEF DESCRIPTION OF THE FIGURES

This plant is approximately 6 years old from the time of mericloning, shown planted in an 8 by 8 cm container.

FIG. 2 illustrates, as nearly true as it is reasonably possible to make the same in color photographs of this type, the typical foliage of ‘SPCDW1510’.

FIG. 3 illustrates, as nearly true as it is reasonably possible to make the same in color photographs of this type, the typical inflorescence and flower of ‘SPCDW1510’.

BOTANICAL DESCRIPTION OF THE PLANT

The following observations and measurements made in June of 2016 describe averages from a sample set of six specimens of six year-old ‘SPCDW1510’ plants grown in a greenhouse in Honselersdijk, the Netherlands. Temperatures were approximately 23 degrees Celsius during the day and 19 degrees Celsius at night. No photoperiodic or chemical treatments were given to the plants. No artificial light was given to the plants.

Those skilled in the art will appreciate that certain characteristics will vary with older or, conversely, with younger plants. ‘SPCDW1510’ has not been observed under all possible environmental conditions. Where dimensions, sizes, colors and other characteristics are given, it is to be understood that such characteristics are approximations or averages set forth as accurately as practicable. The phenotype of the variety may differ from the descriptions set forth herein with variations in environmental, climatic and cultural conditions. Color notations are based on The Royal Horticultural Society Colour Chart, The Royal Horticultural Society, London, 2015 (sixth edition).

A botanical description of ‘SPCDW1510’ and comparisons with other varieties of Vanda are provided below.
